Contrary to the beliefs of many, the amount of free mathematics information available for low-income country researchers, including electronic scientific journals and databases, is indeed substantial. However, whereas information resources are easily available for northern/western universities, researchers at universities in low-income countries have to work hard for their treats.
The scientific information available for low-income countries is scattered among a large number of providers, websites, access methods, price models, and country- or institution-specific programmes. It is therefore quite hard for individual researchers to see the whole picture and establish what actually is available and what is not. Some resources are aimed primarily at disciplines other than mathematics but nevertheless contain extremely important and high-ranking mathematics journals.
In order to find suitable documents it’s extremely important to have access to a comprehensive reference database. Luckily enough both the major databases in mathematics, MathSciNet and ZbMATH, provide free access for many institutions in low-income countries.
This is a list of relevant sites that contains important and crucial mathematics resources, especially journals:
